Seeking the optimal posture of the seated lumbar spine

Abstract

AbstractProlonged sitting with poor posture is associated with the development of lower back pain. Ergonomic texts for physiotherapists contain diverging and confusing views on recommended postures for the lumbar spine when seated that will promote postural health and optimal functioning of the lumbar spine. A review of the literature reveals that proponents of both the lordosed and kyphosed lumbar seated position use similar arguments with contradictory conclusions. The arguments of those advocating the kyphosed lumbar seated posture are, however, often anecdotal and unsubstantiated by research. This paper evaluates the confl icting views and concludes that the lordosed seated posture, regularly interspersed with movement, is the optimal sitting posture and assists in maintaining lumbar postural health and preventing low back pain.
